• What Happens If The Generator Set Is Under-Loaded For A Long Time?

  Apr 10 , 2026

    What happens if a diesel generator set is overloaded for a long time? The set can operate at overload power for up to 1 hour. However, if the overload (exceeding rated power) continues for too long, the following conditions may occur: Cooling system overheating – coolant temperature becomes too high. Generator winding overheating – motor life is reduced. Lubricating oil viscosit...

• How To Solve Troubleshooting "Frequency Low" Alarm On Diesel Genset ?

  Jan 29 , 2026

  Troubleshooting "Frequency Low" Alarm on a Diesel Genset Controller A low frequency indication typically means the generator is running below its rated speed (e.g., below 50 Hz for 50 Hz systems or 60 Hz for 60 Hz systems). This is usually a speed/engine issue, not solely an electrical one, as frequency is directly proportional to engine RPM.   Immediate Actions & Safety First 1.  En...
